Apologies if this is not the right place for this topic. I don't have OCD and may not have OCPD but this thing seems to belong both there and here.
I just wanted to share that I feel like I am a reluctant completionist.
I have to finish all the movies, video games(101%), books and whole series of shows and anime that I started, even the ones that I begin to hate or lose all interest in (which is most of them).
I waste time completing not-so-important things that could have been used for starting more important work.
I try to finish foods and other consumable products as soon as I buy them instead of conserving them for future.
I end up only starting and doing things to complete them when their main objective was enjoyment or to pass time, like traveling or learning a musical instrument.
I get very distressed if I am not able to complete things.

I hate all of this. This thing is deteriorating the quality of my life an I don't feel enough control over it but I'm trying my best.
Does anyone else do this? Any tips on how to deal with it?
